Algebra I Practice Test Inequalities and Absolute Value Name Date Unit 3 Period Vocabulary: Define each word and give an example. 1. Less Than 2. Absolute Value Equation 3. Compound Inequality Short Answer: 4. Solving a linear inequality is similar to solving linear equations with what one exception? 5. Describe and give an example of the difference between a compound inequality that is an “or” statement and a compound inequality that is an “and” statement. 6. Explain why an absolute value equation can have two solutions. Illustrate with an example. Review: 7. Find the first and third quartiles and interquartile range for the following set of data: 2, 5, 5, 8, 10, 15, 20, 22, 25 Q1 = Q3 = IQR = 8. Name the property illustrated by a ( b + c ) = ab + ac . 9. Solve the equation. 8 p 8 = 2 ( 5 2 p ) + 10 10. For Vera’s cellular phone service, she pays $32 a month, plus $0.75 for each minute over the allowed minutes in her plan. Vera received a bill for $47 last month. For how many minutes did she use her phone beyond the allowed minutes?
